Today, you will be experimenting with rigid transformations and exploring their connections to proving congruence.
Use a sequence of rigid transformations to map onto three other triangles. (1) Create by reflecting over the line through points B and C. (2) Create by rotating 90 degrees clockwise about point A'. (3) Create a vector from (0, -2) to (4, -4) (4) Translate along the vector you just made to create . What do you notice about the and ? What mathematical statement can you now make about these two triangles? Can you find a different sequence of rigid transformations that will map onto ?
